When you think of Detroit Lions football under Dan Campbell, one word comes to mind: tough. And that toughness starts in the trenches. From Day One, the Lions' philosophy has been simple—run the ball and stop the run. You can't do either without a dominant offensive and defensive line. Now, according to General Manager Brad Holmes, the Lions have never been deeper on both sides of the line.

"This is probably the deepest that we've been on both sides of the line of scrimmage," Holmes told "Good Morning Football" on Friday. "We were able to get younger on the offensive line, and we've got a lot of good depth in the secondary and on defense as a whole. With what we already had established on offense, we feel really, really good about where we're at right now."

That confidence is backed by a clear offseason strategy. The Lions made a deliberate youth movement along the offensive line, parting ways with veterans Graham Glasgow (33) and Taylor Decker (32). In their place? Free agent signing Cade Mays (27) and first-round draft pick Blake Miller (22).

"In terms of his makeup and intangibles, he fits us like a glove," Holmes said of Miller. "You're talking about a guy who rarely missed a practice—and when he did, he didn't feel great about it because he felt like he was letting his teammates down. Those are the type of guys we want in our locker room."

But the depth doesn't stop there. Veteran Larry Borom gives the Lions a reliable swing tackle option after starting 11 games last season. Ben Bartch and Juice Scruggs add experienced insurance if injuries strike. And with a crop of young guards developing behind them, Detroit is building a pipeline of talent that could anchor the line for years to come.

The message is clear: The Lions are doubling down on the gritty, physical identity that defines them. And for fans who love the battle in the trenches, this team is built to deliver.
